Function code data = 0
Converter running -- RUN
This output signal comes ON when the converter
outputs a voltage (during boosting of DC link bus
voltage).
Note: If the DC link bus voltage drops due to a
momentary power failure, the converter comes to a stop,
turning the
RUN off.
Function code data = 1
Converter ready to run -- RDY
This output signal comes ON when the converter
becomes ready to run after the main circuit power is
supplied and a
RUN command is entered.
This signal is used as an interlock signal for a run
command of the inverter connected with the converter,
as shown in the basic connection diagram.
Function code data = 2
Source current limiting -- IL
This output signal comes ON when the current
command value is limited by current limiter values
(H15 to H18).
The hysteresis width for prevention of chattering of
signal output is set with E17 "Current limiting signal."
Function code data = 3
Lifetime alarm -- LIFE
This output signal comes ON when the cumulative run
time of any of the DC link bus capacitor (smoothing
capacitor), electrolytic capacitors on the control printed
circuit board, and cooling fan inside the converter has
approached the end of the service life.
The life judgment depends on the following. The
cumulative run time information can be monitored on
the maintenance info screen in real time.
Part Life judgment level
DC link bus capacitor Cumulative 87,600 hours
(Cumulative power-on hours of
main circuit)
Electrolytic
capacitors on control
printed circuit board Cumulative 87,600 hours
(Cumulative control power-on
hours of converter)
Cooling fans 87,600 hours
This is the estimated life of the
cooling fan at ambient
temperature of 30°C.
This function should be used merely as a guide. Daily
inspection and periodic inspection are necessary to
avoid failures and to continue reliable operation over a
long time.
Function code data = 4
Heat sink overheat early warning -- PRE-OH
This signal comes ON when the temperature of the heat
sink reaches a temperature 5°C lower than the "heat
sink overheat alarm (
0h1
)" level (X°C).
The heat sink overheat alarm level (X°C) varies
according to the combination of the converter capacity
and the current rating level (MD or LD mode), and it is
fixed within the range of approximately 70°C to 110°C.

Overload early warning -- PRE-OL
This output signal comes ON when the converter
overload reaches the converter overload early warning
level specified by E15. For details, refer to the
description of E15.

Power running -- DRV
Function code data = 7
Regenerating -- REG
The DRV or REG output signal is turned ON during
power running or regeneration of the converter,
respectively. During no-load running (with current
command within 3%), the converter is in the
RUN state
and both the DRV and REG are turned OFF.
The state can be monitored on the running screen
(GUIDANC) of the keypad.
